When using a
QFileDialog to save a file and to specify the extension (like *.pdf) and the user types in a name without this extension, also the saved file hasn't this extension.
QFileDialog fileDialog(this, "Choose file to save"); fileDialog.setNameFilter("PDF-Files (*.pdf)"); fileDialog.exec(); QFile pdfFile(fileDialog.selectedFiles().first());
now when the user enters "foo" as the name, the file will be saved as "foo", not as "foo.pdf". So the
QFileDialog doesn't add the extension automatically. My question: How can I change this?
You could use QFileDialog::setDefaultSuffix():
This property holds suffix added to the filename if no other suffix was specified.
This property specifies a string that will be added to the filename if it has no suffix already. The suffix is typically used to indicate the file type (e.g. "txt" indicates a text file).
